Great Green Fleet Trial Launched by U.S. Navy in Pacific
July 20th, 2012 by 
The U.S. Navy this week held military exercises in the Pacific Ocean that used an expensive blend of biofuels and conventional fuels to power 71 aircraft and three warships, part of an ongoing effort by the Navy to develop alternative fuels for its global operations.
The so-called “Great Green Fleet” initiative is a top priority of Navy Secretary Ray Maybus, who contends that the U.S. military must eventually free itself from dependence on fossil fuels “because unpredictable and increasingly volatile oil prices could have a direct impact on readiness.” But numerous critics, including U.S. Senator John McCain, criticize Maybus’ initiative as unnecessary and costly, noting that the 50-50 biofuel/conventional fuel blend costs $26 a gallon — more than six times the cost of conventional fuels.
A Defense Department study said that the military will spend $2 billion more annually if it continues to pursue its biofuels experiments. About 90 percent of the biofuels was rendered from cooking oil waste and the remaining 10 percent was refined from algae. Maybus, speaking aboard the aircraft carrier USS Nimitz, contended that the rising costs of oil and breakthroughs in biofuel production will eventually narrow the price gap between conventional and alternative fuels.
